William Henry Bragg was born in Wigton, Cumberland, England in 1862, and he graduated from Trinity College, Cambridge in 1884 as third wrangler. In 1885, he became a professor of mathematics and experimental physics at the University of Adelaide in Australia. In 1896, he demonstrated the importance of X-rays to doctors, and he returned to England in 1908, bringing his son Lawrence Bragg with him. In 1909, he became chair of physics at the University of Leeds, and, in 1915, he and his son were jointly awarded the Nobel Prize in Physics for using X-ray diffraction to analyze the structure of a crystal. He was knighted in 1920, and he died in 1942.
